SOT-23-3

The SOT-23-3 is the most widely used surface-mount transistor package in the world. With just three pins at 0.95mm pitch and a tiny 2.9 x 1.3mm body, it houses MOSFETs, BJTs, voltage references, small LDO regulators, and single-gate logic ICs. Its compact size and excellent thermal performance make it the go-to package for space-constrained designs, from smartphones to industrial controllers.
